hey, I just got to lv. 58 but don't know witch zones I should do in order to get the full story. could you please tell me what the zones are in order and what lv I should be to go to them? #burning crusade

On a serious note, you're going to out level the content long before you complete the zones. If you're just trying to level, you'll be best served by clearing out 2-3 levels of quests and moving on to the next zone. If you're going for completionism, I found the zones rather entertaining and probably worth doing the full questlines for if you've never seen them..
